BACKGROUND: Contiguous skin inflammation is a poorly described entity. It constitutes a cutaneous manifestation of an underlying ongoing process (infectious, inflammatory or neoplastic). Sinusitis is a known cause. PATIENTS AND METHODS: We report the case of a 70-year-old patient consulting for an ongoing centrofacial inflammatory plaque. Cutaneous biopsy revealed a polymorphic inflammatory infiltrate, and cutaneous microbiological specimens were negative. A facial CT-scan showed left maxillary sinusitis...

To clarify the conflicting recommendations for care of blowout fracture (BOF), a prospective randomized study is required. Here, we present a prospective randomized pilot study on BOF. This article aimed to evaluate which computed tomography (CT) findings predict late functional and/or cosmetic symptoms in BOF patients with ≥ 1.0 mL herniation of orbital content into maxillary and/or ethmoidal sinuses. It also aimed to evaluate which patients with BOF would benefit from surgical treatment or observational follow-up...

We describe a case of nasal myiasis due to Musca domestica in a 97-year-old Peruvian farmer with a previously undiagnosed mucocutaneous leishmaniasis. Initial attempts to remove the fly larvae using manual extraction with a toothed forceps and normal saline irrigation were unsuccessful. On subsequent nasal irrigation with ivermectin solution, the patient self-expulsed approximately 50 larvae within 15 min. He also received a course of oral ivermectin. A post-treatment CT scan revealed clear sinuses. Here, we propose that ivermectin irrigation is a simple and effective treatment for nasal myiasis...

BACKGROUND: Registration accuracy is a main factor influencing overall navigation accuracy. Standard fiducial- or landmark-based patient registration is user dependent and error-prone. Intraoperative imaging offers the possibility for user-independent patient registration. The aim of this paper is to evaluate our initial experience applying intraoperative computed tomography (CT) for navigation registration in cranial neurosurgery, with a special focus on registration accuracy and effective radiation dose...

Anatomical uniqueness plays a significant role in the personal identification process of unknown deceased. Frontal sinuses have been widely used in the past decades for this purpose, mostly using 2D X-ray techniques. However, the modern 3D CT-based segmentation methods may help in developing novel and more reliable methods of identification. This study aims at assessing the anatomical uniqueness of frontal sinuses through the 3D model registration. Thirty subjects who underwent two maxillofacial CT scans (interval: 1 month to 5 years) were selected from a hospital database...

We present a case of a 59-year-old man with acute abdominal pain and progressive shortness of breath. A focused assessment with sonography for trauma scan showed free fluid in the hepatorenal recess and in the recto-uterine recess. Later, due to clinical deterioration and the differential possibility of a pulmonary embolism or aortic dissection, a CT scan was performed which revealed large pericardial effusion. This, together with a dilated vena cava inferior and portal system, raised the suspicion of cardiac tamponade...

Cerebral venous thrombosis is a rare condition which constitutes 0.5% to 2% of all types of stroke and carries a mortality of up to 20% to 50%. It leads to cerebral edema, infarction, hemorrhage and venous hypertension. Clinically the diagnosis is confirmed using enhanced computed tomography (CT) angiography which demonstrates an empty delta sign in cerebral veins, particularly in the superior sagittal sinus. However, postmortem CT (PMCT) findings on cerebral venous thrombosis have not been documented in the literature...

Functional Endoscopic Sinus Surgery (FESS) is one of the most common outpatient surgical procedures performed in the head and neck region. It is used to treat chronic sinusitis, a disease characterized by inflammation in the nose and surrounding paranasal sinuses, affecting about 15% of the adult population [1]. During FESS, the nasal cavity is visualized using an endoscope, and instruments are used to remove tissues that are often within a millimeter of critical anatomical structures such as the optic nerve, carotid arteries, and nasolacrimal ducts...

PURPOSE: This study was to evaluate whether optic nerve damage occurs in eyes with adjacent chronic sinusitis. METHODS: Data were collected from eighty-eight eyes of 46 chronic sinusitis patients and 93 eyes of 57 normal controls. Visual sensitivity using standard automated perimetry (SAP) and inner retinal thickness using optical coherence tomography (OCT) were measured. The Lund-Mackay system was used to quantify radiographic findings on the ostiomeatal unit CT scan with a numerical score representing the severity of sinusitis...

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a heterogeneous inflammatory disease usually characterized by chronic eosinophilia in the sinonasal mucosa, which often requires glucocorticoid (GC) therapy. However, the therapeutic response varies markedly between individuals. The objective of this study was to evaluate the diagnostic values of sinus computed tomography (CT) for GC-sensitivity in patients with CRSwNP. Methods: We conducted a prospective, single-blinded study of 47 consecutive patients with CRSwNP...

INTRODUCTION: Paragangliomas, defined as extra-adrenal chromaffin-cells tumors, are rarely located in the retro-peritoneum. Clinical presentation is similar to pheochromocytoma, and mainly depends on the producing character of the tumor. Positive diagnosis requires plasmatic and urinary hormonal assays. Radiological and isotopic explorations are essential before surgery. The only curative therapeutic strategy is surgical, associated to peri-operative prevention and monitoring of the frequently reported hemodynamic and cardiovascular disorders...

INTRODUCTION: Functional endoscopic sinus surgery for frontal sinus disease has obviated the need for external approaches. Special circumstances such as acute infection with orbital involvement or significant lateral sinus disease frequently require adjunct access. We describe the clinical outcomes of a combined upper eyelid crease and endoscopic approach for lateral frontal sinus disease with orbital extension. METHODS: A retrospective case series of 7 patients who underwent a combined lid crease approach for frontal sinus disease with orbital extension between April 2012 and October 2016 was performed...

PURPOSE: A novel precision three-dimensional (3D)-printed paranasal sinus-skull base anatomical model was generated with a commercial grade desktop 3D printer. A specific page-turning pattern was employed in this model, to display the internal spatial structure of the paranasal sinus. METHODS: The CT image data of paranasal sinus were imported into the Mimics software to construct a 3D digital paranasal sinus-skull base model. Then, the model was sliced in the coronal position and loaded into the 3D printer to print each slice of the paranasal sinus-skull base model at a ratio of 1:1 in size...

HYPOTHESIS: The retrofacial approach is a feasible approach to the round window niche and that the Round window-Sigmoid sinus line will help determine the feasibility of retrofacial approach for cochlear implantation unless there is a very high jugular bulb. BACKGROUND: When the round window cannot be visualized by facial recess approach during cochlear implantation, other conservative techniques can be used to improve visualization such as the retrofacial approach...
